Question

c programming

Given the function heading and variables below:

void myFunction(int a, char b)

int num =10;

char letter = 'Q';

Are the following statements valid or invalid function calls? If not, why?

a. myFunction(num, letter);

b. num = myFunction(num, letter);

c. myFunction(10, 3.14);

d. myFunction(num, '!');

e. printf("%c", myFunction(15, letter, num));

Answer 1

a. myFunction(num, letter);
valid.

b. num = myFunction(num, letter);
invalid. Because myFunction is not returning anything.

c. myFunction(10, 3.14);
invalid. Because second argument should be of type char.

d. myFunction(num, '!');
valid.

e. printf("%c", myFunction(15, letter, num));
invalid. Because myFunction is not returning anything.
